Could you provide with more information such as how to replicate, which version of prat you are using, and try testing it with only prat installed.
The way taint works is, blizzard likes to point fingers at whomever it wants, and isn't always the case of who actually is triggering/causing the taint.

Not sure if this is a proper place to reply, but I found a way to reproduce the taint (I do get different error message, but still taint). The error happens if I have Prat enabled, and doesn't happen if Prat is disabled.

Steps to reproduce

1. Get in the raid (two people are enough)
2. Get in any combat (i.e. random creature)
3. Press O (opens social) and select Raid tab

WoW version: WotLK Classic, 3.4.1.47800
Prat version: ## Version: 3.9.1
